EDWVARD P. ZEIDLER, OF CLEVELAND, OHIO.

DRUM.

SPECIFICATION forming part of Letters Patent No. 609,068, dated August16, 1898.

Application filed March 1 9 l 8 9 8.

To all whom it may concern:

Be it known that I, EDWARD P. ZEIDLER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Drums; and I do declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same.

My inventionrelates to improvements in drums; and the object of theinvention is to provide a drum in which I am enabled to have either anorchestra-drum or a band-drum at pleasure by merely making some slightand convenient adjustment of the parts to convert the drum from onecharacter to another, all as hereinafter described, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of myimproved drum. Fig. 2 is a central cross-sectional elevation thereof.Fig. 3 is a detail View of the deadeningbridge.

It will be observed in Fig. 2 that there are three distinct and separateheads A, B, and O, which are always present in the drum, and all may beused at one time, or the head A may be used with either of the others ata time, as may be desired.

The combinations for a banddrum are heads A and O, in which case thesnares b for head B are relaxed by means of the snare straining andreleasing mechanism 1), hereinafter more fully described, and the snaresc tightened. The combinations for a snaredrum distinctly are the heads Aand B, with the snares l) tightened and the snares 0 relaxed andrelieved, also as hereinafter more fully described. For other purposesand to obtain a sound distinctly peculiar to a threeheaded drum of thiskind I tighten all the heads and snares at the same time and use themall together, and there is as a result of this construction a distinctand novel sound given forth that cannot be obtained by a twoheaded drumand that may be said to be of a quality intermediate of the orchestraand band drums. This drum, therefore, is always complete and onlycomplete when all the heads and parts are brought together and availablefor use substantially as herein shown and de Serial No. 674,473. (Nomodel.)

scribed, and it is distinctly and essentially a three-headed drum, inwhich there is a central or intermediate head preferably midway betweenthe two outer headsA and O and having a place of service in conjunctionwith said outer heads or with the head A alone, as may be wanted.

Now returning to the snare straining or tightening mechanism it will beseen that the snares b have tightening-screws b, and which engage athreaded clamp 12 that fastens the ends of the snares b, and by rotatingthe said screw in one direction the snares are tightened and in theopposite direction they are released, and there may be more or lesstension given to the snares as they may need, or they may be so relaxedas to be thrown practically out of use for the time, as occurs when thehead B is not used, as hereinbefore described. The snares c are fastenedby screws 0 and, cross-clamps 0 similar substantially to the screws andclamps Z) and b and in like manner serve to tighten or release thesnares c. In this latter case, however, when the lower head 0 is notbeing used the snares c are released and the sound-deadening bridge 0 ofindia-rubber or other material, is interposed between the snares and thehead G, preferably at opposite sides of the drum, so as to entirelyrelieve the snares from the drum-head and take them out of soundingconnections.

A series of clamping-screws D, connecting the outer heads, are shown inFig. 1, said screws engaging clamps d at their outer extremities and acentral threaded T-shaped post at, into the arms of which both thescrews:D are adj ustablyengaged. The heads or outer extremities of thesaid screws D are constructed to be engaged to turn by a wrench, and bytightening or releasing these screws the several heads A, B, and C aretightened or released. It will be observed also that the rim E of theupper drum'-section between heads A and B is provided with a fewairholes, relatively a, while the lower rim Fbetween heads B and O ismore numerously perforated with holes f.

IVhatI claim as new, and desire to secure by Letters Patent, is-

1. A drum provided with three several heads, two of which are outerheads and one an intermediate head, and snares for the in termediate andlower heads, substantially as described.

2. The drum having three separate heads and the middle head providedwith snares, substantially as described.

3. A drum having three heads and snares for the middle and lower headsand separate means to tighten and release said snares whereby anorchestra or a band drum may be made, substantially as described.

4. Adrum constructed in two sections horizontally permanently securedtogether and having a head between the two sections provided with snaresand upper and lower heads, substantially as described.

5. A drum having three heads, snares for the middle and lower head andmeans interposed between the lower head and its snares to deaden thesound of said head, and means to tighten the snares of the middle head,substantially as described.

Witness my hand to the foregoing specification this lth day of March,1898.

EDWARD P. ZEIDLER.
